Analysis Functions

The ScopeMath demo includes many functions that illustrate how to use MATLAB to analyze your data. The functions show you how to use common MATLAB operators, built-in functions, and M-files to analyze your data. The basic analysis functions are grouped into these categories:

 

 

The following is a list of all the M-files and links to HTML pages that display what the text would look like in the MATLAB editor.

M-File Name
